Three gang prism mould to produce 50x50x250 mm specimens.
....To observe several spectra: continuous spectrum, emission spectrum, absorption spectrum and solar spectrum.
....The instructional material includes a complete set of drawings. The geometric models support the learning process by providing an introduction to technical drawings: from the solid model to the more abstract representation of the three views in a technical drawing. It presents each model in three views, as well as its 3D view and production drawing. The set contains 18 aluminium drawing models. The prismatic models have cut-outs parallel to, and at an angle to, the edges of the prisms. The models are precision-manufactured and are suitable for measurement exercises as well as drawing exercises.
....A beam of white light will be separated into colors by a prism and formed into light band composed of red, orange, green, indigo and purple. It is used to demonstrate dispersion of light in middle school physics and primary school nature.
